Description

A kind of high-pressure shock absorber of twin-tub band floating piston assembly
Technical field
The present invention relates to a kind of vehicular shock absorber that improves stability in the Vehicle Driving Cycle process, be specifically related to a kind of high-pressure shock absorber of twin-tub band floating piston assembly.
Background technique
Concussion when vibration damper (Absorber), vibration damper are mainly used to suppress bounce-back after the spring shock-absorbing and from the impact on road surface.Through uneven road surface the time, although the shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Vibration damper is too soft, and vehicle body will jump up and down, and vibration damper will bring too large resistance too firmly, hinders the spring normal operation.In the retrofit process about suspension system, hard vibration damper will be arranged in pairs or groups mutually with hard spring, and the hardness of spring is closely bound up with car weight, therefore the harder vibration damper of the general employing of heavier car.With draw the device that joins of shake bent axle, the torsional shaking of the bent axle that is used for contending with (be the impact force of bent axle subject cylinder igniting and the phenomenon that twists).
The structure of vibration damper is to insert in the cylinder with the piston rod of piston, is full of oil in cylinder.Throttle orifice is arranged, so that the oil in two-part space that is separated by piston can complement each other on the piston.Damping produces during by throttle orifice at the sticking oil of tool, and throttle orifice is less, and damping force is larger, and the viscosity of oil is larger, and damping force is larger.If the throttle orifice size is constant, when the vibration damper operating rate was fast, the absorption that conference affects impact was crossed in damping.Therefore, in the outlet port of throttle orifice a discoid leaf spring valve is set, when pressure became large, valve was backed down, and it is large that the throttle orifice aperture becomes, and damping diminishes.Because piston is bidirectional-movement, so in the both sides of piston the leaf spring valve is housed all, is called respectively compression valve and rebound valve.
Concussion when vibration damper is mainly used to suppress bounce-back after the spring shock-absorbing and from the impact on road surface.Through uneven road surface the time, although the shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Vibration damper is too soft, and vehicle body will jump up and down, and vibration damper will bring too large resistance too firmly, hinders the spring normal operation.In the retrofit process about suspension system, hard vibration damper will be arranged in pairs or groups mutually with hard spring, and the hardness of spring is closely bound up with car weight, therefore the harder vibration damper of the general employing of heavier car.With draw the device that joins of shake bent axle, the torsional shaking of the bent axle that is used for contending with (be the impact force of bent axle subject cylinder igniting and the phenomenon that twists).
At present, the vibration damper that automobile uses all belongs to hydraulic damper basically, its principle is, when vehicle frame and vehicle bridge are done when moving back and forth in the cylinder barrel of reciprocal relative movement youngster piston at vibration damper, fluid in the vibration damper housing just flows into another inner chamber from inner chamber by some narrow holes repeatedly, at this moment, the interior friction of the friction of liquid and inwall and fluid molecule just forms the damping force to vibration.
Vibration damper can be divided into two-cylinder type and single casing by its structure.Two-cylinder type refers to that vibration damper has inside and outside two cylinders, and piston moves in inner casing, because the entering and extracting out of piston rod, the volume of oil increases and contraction thereupon in the inner casing, therefore will be by exchanging to keep the balance of oil in the inner core with outer shell.So dual tube shock absorber is provided with valve.The balance that folding and unfolding keeps oil pressure in the vibration damper of opening by valve, so just require vibration damper in use can be in well dynamically balanced state, because the quality of vibration damper is large, connector element is complicated, performance requirement is strict, usually all often have complicated structure characteristic and annexation is installed, what require also simultaneously that installing and using of vibration damper can be enough is firm, to improve the Security of driving transportation.
When vehicle jolts frequent and amplitude when larger, hysteresis is filled up in the circulation of cylinder body internal damping oil, very easily occurs vacuum area in the cylinder body, and the piston original lower position of can not working again is so that compression damping is increased to unallowable numerical value.And, the abnormal sound that noise and vibrations are sent appears easily, have a strong impact on damping effect.Chinese patent, the patent No. is 200620141855.7, the patented technology of " with the barrel type hydraulic shock absorber of floating piston " by name, bottom at cylindrical shell is equipped with float piston device, substantially the problems referred to above have been solved, but this technology is existent defect still, as it is too small to be filled with the volume of pressurized gas, and the vibration damper that can not adapt to big connecting rod uses.
Chinese patent, the patent No. is 200820164650.x, " double-cylinder high-pressure vibration absorber " by name can adapt to the use of the vibration damper of big connecting rod, this patent solution is: in the chamber of interior clutch release slave cylinder floating piston is set, clutch release slave cylinder arranges gas cylinder outward, the gas cylinder inwall communicates with the clutch release slave cylinder bottom with space between the clutch release slave cylinder outer wall, and whole clutch release slave cylinder bottom and the space of whole gas cylinder inwall between the clutch release slave cylinder outer wall are filled with high-pressure inert gas.The main technology point of this patent is to add a gas cylinder outside clutch release slave cylinder, and is large by the volume of air chamber, guarantees the stroke of air pressure, thereby can satisfy to greatest extent the stroke of piston rod.When using the vehicle of this kind vibration damper to meet continuous bumpy sections, the shock-absorbing capacity of this vibration damper is subject to very big test, although damping performance is compared with having before very large lifting, but damping effect is partially hard, the interior driver and passenger of operator cabin are done not feel like oneself, vibration damper internal damping performance is still waiting to improve, and for large stroke, the big connecting rod Special shock absorber also has very large improved space.
Thereby satisfy to greatest extent the stroke of piston, improved the damping performance of vibration damper, use in the vibration damper of suitable all size connecting rod, the present invention is novel in design, unique, and low cost of manufacture, is a kind of desirable vibration damper.
